Bacteriological analysis of drinking water by using MPN method

Abstract :

Amphibians play an important role in the ecological cycle of the agroecosystem. The declining trend and disappearance of amphibian population in ponds are influenced by several factors such as climatic changes, fertilizers, pesticides and invasion of exotic plants. Time constrained VES (Visual Encounter Survey) method involves systematic search of an area. A total of 9 species of anurans were recorded in the present study in Nagapattinam district. They belonged to seven genera and four families of amphibians. Studies on the microhabitats revealed that most of the amphibians preferred the water bodies and edge of the water as the micro habitat. In the present study Hoplobatrachus crassus, Fejervarya limnocharis and Microhyla ornata were encountered in all types of microhabitats when compared to other species of amphibians.

Keywords:

Amphibians, GPS, Micro habitats, VES Method and Nagai District.
